Abstract Synthesis of two new amino acids, containing pyran rings, is reported from carbohydrate derivatives. The cis-3-amino-pyran-2-carboxylic acid (cis-APyC) was prepared from (R)-glyceraldehyde derivative, using nucleophilic substitution reaction for pyran ring formation. Similarly, the trans-3-aminoxy-5,6-dihydro-2H-pyran-2-carboxylic acid (trans-AmPyC) was prepared from diacetone glucose (DAG)
摘要 报道了从碳水化合物衍生物合成两种含有吡喃环的新氨基酸。顺-3-氨基-吡喃-2-羧酸(cis-APyC)由(R)-甘油醛衍生物制备,使用亲核取代反应形成吡喃环。类似地,反式-3-氨氧基-5,6-二氢-2H-吡喃-2-羧酸(反式-AmPyC)由双丙酮葡萄糖(DAG)制备,使用闭环复分解(RCM)反应形成环。图形概要
